Abstract: Dominance hierarchy is the core feature of social animals, and in novels, which serve as the presentation and reflection of social reality, fictional characters are also portrayed as in different social classes and the elite (upper class) greatly influence the public in human societies. In previous literature, however, there were very few quantitative studies on the characters personality and social class, and now the literature intelligent analysis model provides a reliable method. Based on artificialintelligence method, the represent research predicted the Big-Five personality scores of 116 characters in Louise Cha novels, and compared them among those from different social classes. The results showed that the upper class revealed a higher level of Agreeableness and a lower level of Neuroticism. In addition, men in the upper class (vs. lower class) revealed higher Openness, while women's Openness in the lower class (vs. upper class) was comparable. The current findings, such as the upper class Agreeableness, are consistent with the traditional ethics and observations, and also demonstrate the social ideal in literature works. The present research provides a new method for the psychology of social class, and sheds light on the artificialintelligent field in identifying novel characters personality.

Key words: literature intelligent analysis, dominance hierarchy, BigFive personality, novel characters, Louise Cha
